[flexcoders] mx:repeater RangeError when recycleChildren="true"

[stu_bot]

Hi,

I'm having an issue using an mx:repeater to display the tabs inside an
mx:TabNavigator. Using recycleChildren="true" seems to have a problem
when the underlying dataProvider (an ArrayCollection) is changed.

I've reduced the problem down to the following code:


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; >
        
        <mx:Script>
                <![CDATA[
                        import mx.collections.ArrayCollection;
                        
                        [Bindable]
                        public var a:ArrayCollection = new 
ArrayCollection([1,2,3]);
                ]]>
        </mx:Script>
        
        <mx:Button click="a.addItem(4)" label="Add tab" />
        
        <mx:TabNavigator>
                <mx:Repeater id="rptr" 
                        dataProvider="{a}" 
                        recycleChildren="true">
                        
                        <mx:VBox label="{rptr.currentItem.valueOf()}" 
width="200" />
                </mx:Repeater>
        </mx:TabNavigator>
        
</mx:Application>


Clicking the button results in "RangeError: Error #2006: The supplied
index is out of bounds."

When recycleChildren="false" I don't get the error.

Has anybody got any suggestions on this one?


Cheers,
